IMPROVBMENT IN VAPOR-CHANDELIERS.

The Schedule referred to in these Letters Patent and making part of the name.

lTo all whom it may concern Be it known that' we, CHARLES E. SMITH' and HENRY J. RICE, both ot Columbus, in the county of Franklin and State of Ohio, have invented certain Improvements in Vapor-Chandeliers; and we do herebydeclarethat the following, taken incounection with the drawing which accompanies and forms part ot' this speeilication, is a description of our invention suti.- cient to enable those skilled in the art to practice it.

Figure 1 is a side elevation of a chandelier made with our improvements applied thereto, the cap o being shown in section, vto display the auxiliary jet beneath the generatingcliamhcr;

Figure 2 is a vertical section of the upper part of the chandelier; p

Figure 3, a similar section of t-he lower part.; and

Figure 4, a perspective view ot'- a modified form of the generating-clianlber.

A' is the vessel or reservoir for supplying the liquid to he vaporized, a pipe, B, extending beneath the same, and furnished with a stop-cock, l).

Below this stop-cock is a wick-pipe, C, filled with wicking or other appropriate material, this pipe communicating with a gaschamber, D, which contains the body of the gas, as it is generated by the means hcreinattcr described.

E E are brass plates or partitions in the tube or chamber D, serving to separate the gas-chambertrom. an air-receiving and heating-chamber, F F, these partitions each having a small' central hole, e, to permit the passage outward ot' the gas, that it may, before reaching-the illuminating burner G, commingle with the oxygen ofthe atmosphere, which is t'ree to enter at the openings H H.

Betbre doing this, however, a portion ot' the gas, as it makes itsexit, under pressure, through the-central openings c in the partitions, is driven into the side oritice 1 in the tube K.

This tube is made about two feet or somewhat less in length, an'd is closed at its inner end 2 and open'at its outer end 3, which is lot-ated outside the. generating-chamber, and 4serves to aord a limiting-jet, L, as seen, to generate the gas for the supply o1 both burners, the tiame of this heating-jet coming directly he'- neath the center ot the chandelier, and, thereby, in

the ,most favorable location for action upon the luid,

as it descends through the wick or drops therefrom, and also sothat one tube likeK may perform duty for as many radial branches, with a burner to cach, as may be made uponthe chandelier. v

Phe orifice l is made somcwl'mt larger than its opposite orifice 4, in order that more gas shall be made to enter at 1 than can make its exit at 4, the excess serving to till to overtiowing the tubeK, and thus feed the Atialne at L.

The remainder of the superheated gas forced through the openings e con'nningles with the oxygen ot' the, air entering at H, and serves for illuminating purposes.

By this construction and mode of operation it is not necessary to have the orifice through which the l auxiliary or heating-jet makes its exit so excessively minute and almostinrisible as has hcretoibre been .the case, such oritces requiring nmch skill t-o make,

and easily becoming clogged or gnnnned up,and with 4ing-tubes or chambers, and also for the purpose of facilitating the heating action in generating' the gis.

1t-is formed with one open-topped chamber, M, in-

side the generatingfchambcr N, small openings g communicating from one to the other.

Now, it is apparent that M must Abecome full enough to overflowat the openings g, bet'ore N and the conductors leading therefrom could receive any ofthe oil, and under ordinary circumstances'this is liever likely to occur.

The length of the Atube K, and its direct contact with' the main tube or gas-chamber, is a teature' ot' great importance.

It will he observed that, excepting where the bends are necessary, ateithcr end, to carry the closed end up into the air-chamber, or to carry the jet or outer end to a propel' position t'or its liame, this tube lies close against the gas-chamber, and on its under side, for a distance ot' some two t'eet or less, according to the size ot' the chandelier, thereby, with its heat, su-

per-heating the vapor which may have been already generated, and with much economy, as 'more ,ot' the oxygen of the air4 is consumed at the illuminating flame, and a bet-ter light and more heat produced.

lt will also be seen .that the oxygen ot' the atmosphere mingles with the gas or vapor which enters the pipe K, and is consumed withit -at the generatinglialne, thus conducing ,to economy in a great degree.

The inner end ot' pipe K forms, it will be seen, a

`chamber, which may be alnn'opriatelyv termed' an pel it at L, where it. is to he burned, and immediately beneath where its jef; first onverted thc (luid into vapor.

It is found by experience that, by our construction' and operation of' This heating-tube, we get about one hundred percent. more heal; from il: than from the same amountof gas in itsvcrude or non-oxygenized sore and with l, l l

gas, a. chamber constructed substantially as shown and described, and oervingr to convey the gas thus oxygenized back two feet, or thereahout, to .the point; where.

-its Hamerst. causes the gas to be generated.

Also, the combination, with the ge.uerating-cham` ber, of a smaller chamber within the same, the two communicat-ingr by holes 0r openings, as and ful' Elle
